Definitions

  • the present invention relates to a method for making paper containers, and more particularly to a method for making heat-insulative paper containers, a heating device for executing the method, and the heat-insulative paper containers made by the method, which relate to a field of commodity processing.
  • the applicant disclosed a method for making heat-insulative paper containers, as shown in TWM 271364, wherein the liquid adhesive and thermo-expandable powder are mixed as the compound coating; and then coat the paper container with the compound coating, or coat the semi-product with the compound coating and then molding into paper the container; and after that, heat the compound coating in the temperature between 100°C and 140°C so as to make the compound coating foam as a foamed layer adhering to the outer surface of the paper container.
  • the paper container is heat-insulative and heat-prevented.
  • the inner film of the paper container is coated with polyethylene. To prevent the inner film from being damaged by high temperature, the heating temperature and the compound coating are limited. Further, the heating temperature and the compound coating should correspond to each other in order to make the heat-insulative paper container.
  • conventional heat-insulative paper containers are coated with a foam layer which is compounded by low-melting-point thermoplastic synthetic resin.
  • the melting point of the foamed layer should be about between 105°C and 135°C. But it will take about 2 to 4 minutes to reach the melting point. In other words, it is uneconomical to foam for such a long time.
  • US 2002/0041046 discloses a method for producing heat-insulative containers.
  • the containers have an outer surface provided with foam material and an inner surface.
  • a heating device is disposed in the container to directly contact the inner surface to foam the foam material.
  • the film is damaged or decomposed by heat due to directly contacting by the heating device. Decomposed film is however toxic.
  • the foam material on the outer surface foams outward freely so that a non-uniformly foamed layer is produced.
  • the present invention provides a method for making heat-insulative paper containers, including steps of:
  • two surfaces of the paper can be coated with the film, and then mold the paper into a paper container.
  • the adhesive is an oil-based polyurethane resin, and a weight of the polyurethane resin accounts for 5% to 20% of a total weight of the polymer material.
  • a heating temperature for foam molding is between 80°C and 200°C; otherwise the heating temperature is above 200°C.
  • the foam molding by heating takes 1 to 5 seconds;
  • the foam molding by heating is covering the outer surface of the paper container with the heating device, and to heat the foam material to foam instantaneously in a manner of directly touching the foam material with the heating device or disposing the heating device closely to the foam material, and then separating the paper container from the heating device immediately after foaming; otherwise, disposing the heating device closely to an inner surface of the paper container so as to instantly heat the inner surface without touching it, so that the foam material on the outer surface foams instantaneously by the heat transmitted from the inner surface, and then separating the paper container from the heating device immediately after foaming.
  • an inner surface of the heating device is formed corresponding to a shape of the outer surface of the paper container, and the heating device is adapted to cover the foam material on the outer surface of the paper container; otherwise, an outer surface of the heating device is formed corresponding to a shape of an inner surface of the paper container, and the heating device is adapted to be disposed inside of the paper container; wherein the heating device is disposed with one of the devices, which include heating wires, infrared lamps, and heat conductors, so as to transmit heat.
  • the heating device can be disposed after the last section of a paper container molding assembly line, so that the heating device makes one of the processes which include covering an outer surface of the paper container, entering inside of the paper container, and covering the outer surface and entering inside of the paper container simultaneously.
  • the heat-insulative paper containers can be produced efficiently and automatically.
  • a method of the present invention includes mixing and blending polyethylene terephthalate or polypropylene 1 with an adhesive 2 to form a polymer material, wherein the adhesive 2 is an oil-based polyurethane resin, and a weight of the polyurethane resin accounts for 5% to 20% of a total weight of the polymer material; heating and extruding the polymer material with an extruder machine 4 to form a film 41, and then coating 5 a surface of paper 6 with the film 41; cooling and laminating 7 the paper 6 with a laminating roller 7, so that the paper is coated with a polyethylene terephthalate film layer or polypropylene film layer 51; continuously coating another surface of the paper 6 with a foam material 80 in a manner of spraying 8, rolling 8' or color printing 8", and then furling 60 the paper after drying, and after that, cutting the paper into a semi-product 61 and then molding into a paper container 62; otherwise, molding the paper into paper container 62', and then
  • the polyethylene terephthalate or polypropylene film layer 51 can resist the temperature of above 200°Cwhen heating the foam material 80, so that the foam material 80 takes a short time to foam as a foamed layer 801 after instantaneous heating H (as shown in FIG. 2-A ). And the inner surface of the paper containers 62, 62' are coatd with the polyethylene terephthalate or polypropylene film layer 51 which can resist high temperature, so that the paper containers 62, 62' are environmental friendly and non-toxic.
  • two surfaces of the paper 6 can be respectively coated with a film 51, 51'.
  • the paper container can be made in steps of mixing and blending 3 polyethylene terephthalate or polypropylene 1, 1' with the adhesive 2, 2' to form a polymer material, as shown in FIG. 3 ; extruding the polymer material to form a film 41, 41' with a extruding machine 4, 4'; coating two surfaces of the semi-product 61 with the film 41, 41' so as to form a film layer 51, 51'; coating one of the surfaces with the foam material 80, and furling 60 the paper 6 after drying, and then cutting the paper 6 into the semi-product 61 (as shown in FIG.
  • the foam material 80 which is coated on the outer surface of the paper container 62, 62', can be heated by a heating device 9, 9'.
  • the heating device 9, 9' can be disposed closely to the outer surface of the paper container 62 (as shown in FIG. 5-A to FIG. 5-C ) or to the inner surface of the paper container 62 (as shown in FIG. 6-A to FIG. 6-C ).
  • the foam material 80 can be heated instantaneously in a manner of directly touching the foam material 80 with the heating device 9, 9' or disposing the heating device 9, 9' closely to the foam material 80, or disposing the heating device 9, 9' closely to the inner surface of the paper container 62, 62' without touching the foam material 80, and the foam material 80 on the outer surface of the container 62, 62' instantly foaming to form as a foamed layer 801 by the heat transmitted from the inner surface, and after that, separating the paper container 62, 62' from the heating device 9, 9', so that the foamed layer 801 of the paper container can foam rapidly so as to enhance the production efficiency.
  • the heating device 9, 9' can be disposed with heating wires 91, 91' (as shown in FIG. 5-A and FIG. 6-A ), infrared lamps 92, 92' ( as shown in FIG. 5-B and FIG. 6-B ), or heat conductors ( as shown in FIG. 5-C and FIG. 6-C ).
  • the heating temperature can be controlled between 80°C and 200°C, or above 200°C, and the heating part of the heating device 9, 9' is formed corresponding to a shape of the outer surface or the inner surface of the paper container 62.
  • the foam material 80 can be covered by the heating device 9, 9' so as to heat the foam material 80 in a manner of directly touching it or being disposed closely to it, as shown in FIG. 5-A to FIG.
  • the heating device 9, 9' can be disposed closely to the inner surface of the paper container 62 so as to transmit the heat to the foam material 80 on the outer surface, as shown in FIG. 6-A to 6-C . Thereby, the foamed layer 801 is then formed, and the polyethylene terephthalate or polypropylene film layer 51, 51', which is coated on the inner and outer surface of the paper container 62, does not be damaged when heating.
  • Said heating device 9, 9' can cover the foam material 80 on the outer surface of the paper container 62, 62' and be disposed closely to the inner surface of the paper container 62, 62' in the same time, so that it is much faster to heat the foam material 80 to foam. Thereby, the object of increasing production efficiency and improving the foam uniformity can be achieved.
  • the heating wires 91, 91' (as shown in FIG. 5-A and FIG. 6-A ), infrared lamps 92, 92' ( as shown in FIG. 5-B and FIG. 6-B ), or heat conductors ( as shown in FIG. 5-C and FIG. 6-C ) can be selectively disposed on the heating device according to the characteristics of the foam material 80 of the paper container 62, 62' . Thereby, the time for foam molding can be shortened to 1 to 5 seconds, so that the production efficiency can be enhanced, and the defection rate can be reduced.
  • Said heating device 9, 9' can be disposed after the last section of a paper container molding assembly line, which is a conventional production apparatus, so as to produce rapidly and automatically.
